Account Security

Securing Your Account

Account hardening involves implementing robust security measures to make your digital accounts resistant to hacking attempts. By adopting a strategic approach to privacy and account management, you can significantly reduce your vulnerability to cyber threats. Here’s how focusing on privacy and minimizing your digital footprint can harden your accounts:

The Importance of Privacy in Security

Privacy is a fundamental aspect of security often overlooked. The principle is simple: what is unknown cannot be targeted. By maintaining a low profile and keeping your digital activities private, you make it harder for potential attackers to identify and exploit your accounts. This approach is akin to wearing full camouflage in a forest—you become less visible and, therefore, less vulnerable.

Minimizing Your Digital Footprint

Having multiple accounts across various platforms increases your attack surface, making it more likely that one of your accounts will be compromised. Each account represents a potential entry point for hackers. By reducing the number of accounts you actively use, you decrease the risk of a successful attack.

Example: Reducing the Target Area

Consider the analogy of shooting at a target. If your target is a large wall (representing many accounts), it is easier to hit. However, if you narrow the target down to a single brick (fewer accounts), the probability of a successful hit decreases significantly. This principle applies to your digital security: fewer accounts mean fewer targets for potential attackers.

Benefits of Account Minimization

  • Reduced Attack Surface: Fewer accounts mean fewer potential entry points for hackers.
  • Easier Password Management: Managing passwords for a smaller number of accounts is more feasible, reducing the risk of weak or reused passwords.
  • Lower Risk of Compromise: With fewer accounts, the likelihood of any single account being compromised decreases.
  • Improved Security Posture: A leaner digital footprint makes it easier to implement and maintain robust security measures across all your accounts.

Best Practices for Account Hardening

  1. Delete Unused Accounts: Regularly review and delete accounts that you no longer use to reduce your digital footprint.

  2. Use Strong, Unique Passwords: Ensure that each of your active accounts has a strong, unique password. Consider using a password manager to generate and store complex passwords securely.

  3. Enable Two-Factor Authentication (2FA): Add an extra layer of security by enabling 2FA on all your critical accounts. This can include SMS-based 2FA, authenticator apps, or hardware tokens.

  4. Regularly Update Software: Keep all your devices and applications up to date to protect against known vulnerabilities. This includes your operating system, web browsers, and any software you use regularly.

  5. Monitor for Breaches: Use services that notify you if your email or passwords have been compromised in a data breach. Examples include Have I Been Pwned? and similar breach notification services.

  6. Use a VPN: A Virtual Private Network (VPN) can add an extra layer of privacy by encrypting your internet traffic and hiding your IP address. This makes it harder for attackers to track your online activities.

  7. Enable Privacy Settings: Take advantage of the privacy settings offered by the platforms you use. This can include limiting data collection, disabling ad tracking, and controlling who can see your information.

  8. Be Cautious with Public Wi-Fi: Public Wi-Fi networks can be insecure and easily compromised. Avoid accessing sensitive information or performing critical tasks when connected to public Wi-Fi unless you are using a VPN.

  9. Educate Yourself on Phishing: Phishing attacks are a common method used to steal login credentials. Learn to recognize phishing attempts and be cautious of suspicious emails and links.

  10. Use Security Questions Wisely: Security questions are often used as a backup method for account recovery. Choose questions with answers that are not easily guessable or discoverable through social engineering or public information.

  11. Regularly Review Account Activity: Monitor your account activity for any unusual or unauthorized access. Most platforms offer ways to view recent login attempts and device activity.

  12. Backup Important Data: Regularly back up important data to an external drive or secure cloud storage. This ensures that you can recover your data in case of a successful attack or data loss event.

Delete Unused Accounts

Deleting unused accounts is a crucial step in hardening your digital security. Unused accounts can serve as potential entry points for attackers, increasing your overall attack surface. By removing accounts that you no longer use, you reduce the risk of unauthorized access and data breaches. Here’s a step-by-step guide on how to delete unused accounts effectively:

Why Delete Unused Accounts?

  1. Reduced Attack Surface: Fewer accounts mean fewer potential targets for hackers.
  2. Lower Risk of Compromise: Unused accounts are often forgotten and may not have strong security measures in place, making them easier to compromise.
  3. Improved Privacy: Deleting unused accounts reduces the amount of personal data stored online, enhancing your overall privacy.
  4. Easier Management: Fewer accounts make it easier to manage passwords, security settings, and monitor for suspicious activity.

Steps to Delete Unused Accounts

  1. Identify Unused Accounts:

    • Review Your Email: Check your email inbox and spam folder for account creation emails and password reset requests. This can help you identify accounts you may have forgotten about.
    • Use a Password Manager: If you use a password manager, review the list of saved passwords to identify accounts you no longer use.
    • Check Your Browser: Review your browser’s saved passwords and auto-fill data for accounts you may have logged into but no longer use.

Never Use Public Wi-Fi without a VPN

Public Wi-Fi networks are convenient, but they can also be insecure and easily compromised. Using a Virtual Private Network (VPN) when connected to public Wi-Fi adds a crucial layer of security, encrypting your internet traffic and protecting your data from potential eavesdroppers and attackers. Here’s why you should never use public Wi-Fi without a VPN:

Why Public Wi-Fi is Risky

  1. Lack of Encryption: Most public Wi-Fi networks do not encrypt the data transmitted over them. This means that anyone on the same network can potentially intercept and read your data, including passwords, personal messages, and browsing history.

  2. Man-in-the-Middle (MitM) Attacks: Attackers can position themselves between you and the Wi-Fi router, intercepting and altering your data. This can allow them to steal sensitive information or redirect you to malicious websites.

  3. Rogue Access Points: Attackers can set up fake Wi-Fi networks with similar names to legitimate ones, tricking users into connecting to them. Once connected, the attacker can capture all your data.

  4. Packet Sniffing: Without encryption, packet sniffing tools can be used to capture and analyze data packets transmitted over the network, allowing attackers to steal sensitive information.

  5. Malware Distribution: Public Wi-Fi networks can be used to distribute malware. Once connected, you may be vulnerable to drive-by downloads or other malware distribution methods.

How a VPN Protects You

  1. Encryption: A VPN encrypts all the data transmitted between your device and the VPN server, making it unreadable to anyone who might intercept it. This includes hackers, ISPs, and even the Wi-Fi provider.

  2. Secure Tunneling: VPNs create a secure tunnel for your data, ensuring that it travels directly from your device to the VPN server without being exposed to public networks. This protects against MitM attacks and packet sniffing.

  3. IP Address Masking: When you connect to a VPN, your real IP address is masked, and you are assigned a new IP address provided by the VPN server. This adds a layer of anonymity and makes it harder for attackers to target you specifically.

  4. Protection from Rogue Access Points: Even if you connect to a fake Wi-Fi network, the VPN encryption ensures that your data remains secure. The attacker would need to compromise the VPN itself to access your information.

  5. Secure Browsing: With a VPN, you can browse the internet securely, knowing that your online activities are private and protected from prying eyes. This is especially important when accessing sensitive websites, such as online banking or email services.

Steps to Use a VPN on Public Wi-Fi

  1. Choose a Reputable VPN Service: Select a VPN provider that offers strong encryption, a no-logs policy, and a large network of servers. Some popular options include ExpressVPN, NordVPN, and CyberGhost.

  2. Install the VPN Software: Download and install the VPN software on all your devices, including laptops, smartphones, and tablets. Most VPN providers offer apps for various platforms, making it easy to set up.

  3. Connect to the VPN: Before connecting to any public Wi-Fi network, open your VPN app and connect to a server. Choose a server location that offers good speeds and reliability.

  4. Verify the Connection: Ensure that your VPN is actively protecting your connection. Most VPN apps will display a connected status and may also show an icon in your system tray or status bar.

  5. Browse Securely: With the VPN active, you can now browse the internet securely on the public Wi-Fi network. Your data will be encrypted, and your online activities will be private.

  6. Disconnect When Done: Once you are finished using the public Wi-Fi network, remember to disconnect from the VPN to free up resources on your device.

Additional Tips

  • Enable Auto-Connect: Many VPN apps offer an auto-connect feature that automatically connects you to the VPN whenever you join a new Wi-Fi network. This ensures that you are always protected without having to manually enable the VPN each time.

  • Use Two-Factor Authentication (2FA): For added security, enable 2FA on your VPN account. This adds an extra layer of protection, ensuring that even if your password is compromised, an attacker would still need access to your second factor (e.g., a code sent to your phone).

  • Keep Software Updated: Regularly update your VPN software and other applications on your device to benefit from the latest security patches and features.

  • Avoid Free VPNs: While free VPNs can offer some protection, they often come with limitations, such as data caps, slower speeds, and fewer server locations. Additionally, some free VPNs may log and sell your data to third parties. Investing in a reputable paid VPN service is generally a better option for ensuring robust security.

Don't Use Autofill

While autofill features offer convenience, there are several reasons why you might choose to avoid using them for entering passwords. Manual entry, whether through copy-pasting or typing, can provide enhanced security and control. Here are some compelling reasons to avoid using autofill:

Enhanced Security

  1. Extra Layer of Security:

    • Unlocking Password Manager: Manual entry often requires unlocking your password manager first, adding an extra layer of security. For example, using fingerprint authentication on a GrapheneOS device ensures that even with physical access to your device, an attacker cannot easily access your stored credentials without your biometric data or passphrase.

  2. Passphrase Protection:

    • Complex and Long Passphrases: Using a passphrase for your password manager enhances security. Passphrases are typically longer and more complex than standard passwords, making them harder to crack. Unlike biometric data, a passphrase cannot be easily stolen or replicated. An attacker would need to coerce you into revealing your passphrase, which is more challenging than, for instance, forcing your finger on a scanner.

  1. Active Engagement:

    • Manual entry grants you more control over when and how your credentials are used. You are actively engaged in the login process, reducing the risk of automatically filling in credentials on phishing sites or malicious pages. This active participation ensures that you are mindful of your security actions, unlike the passive nature of autofill.

  2. Reduced Risk of Phishing:

    • By manually entering your passwords, you are less likely to fall victim to phishing attacks. Autofill can automatically enter your credentials on fake login pages, whereas manual entry allows you to verify the legitimacy of the website before proceeding.
  1. Alternative Access Methods:
    • Relying exclusively on autofill can create a single point of failure. If the autofill feature is compromised or malfunctions, you may lose access to your accounts. Manual entry, whether through copy-pasting or typing, ensures that you always have an alternative method to access your credentials.
  1. Mitigating Shoulder Surfing:
    • In public spaces, autofill can be useful as it mitigates the risk of someone seeing you enter your credentials. However, if you opt for manual entry, ensure you are not being watched by scanning for cameras, angling your phone, and using your body to obstruct the view. If this seems inconvenient, you can use autofill in public or unlock your password manager beforehand, ensuring you are not observed.

  1. Browser and App Vulnerabilities:

    • Autofill features in browsers and apps can sometimes be vulnerable to exploits. Attackers can target these features to steal stored credentials, so it’s important to keep your software up to date and be cautious of any security advisories.

  2. Syncing Issues:

    • If you use a password manager that syncs data across multiple devices, there is a risk of data corruption or unauthorized access during the syncing process. Manual entry eliminates this risk by keeping your credentials local until you actively decide to use them.

  3. Phishing and Keylogging:

    • Autofill can be tricked by phishing sites to enter credentials into fake login forms. Additionally, keylogging malware can capture autofilled passwords, whereas manual entry allows you to be more vigilant and verify the site’s authenticity before entering your credentials.

Best Practices for Manual Password Entry

    1. Use a Reputable Password Manager:

      • Invest in a reputable password manager that offers strong encryption, a no-logs policy, and additional security features such as two-factor authentication (2FA).

    2. Enable Two-Factor Authentication (2FA):

      • Add an extra layer of security by enabling 2FA on your password manager and all critical accounts. This ensures that even if your password is compromised, an attacker would still need access to your second factor (e.g., a code sent to your phone).

    3. Regularly Update and Audit Passwords:

      • Periodically review and update your passwords to ensure they remain strong and secure. Remove any weak or compromised passwords and replace them with new, strong ones.

    4. Be Cautious with Public Wi-Fi:

      • Avoid entering sensitive information or performing critical tasks when connected to public Wi-Fi unless you are using a VPN. Public Wi-Fi networks can be insecure and easily compromised.

    5. Educate Yourself on Phishing:

      • Learn to recognize phishing attempts and be cautious of suspicious emails and links. Phishing attacks often trick users into providing personal information, which can then be used for identity theft or other malicious activities.

    6. Use Strong, Unique Passwords:

      • Ensure that each of your accounts has a strong, unique password. Use a password manager to generate and store complex passwords securely, reducing the risk of password reuse and making it harder for attackers to gain access to your accounts.

The Risks of Staying Logged In All the Time

Remaining logged into your accounts at all times can seem convenient, but it poses several security risks that can compromise your digital safety:

Risks of staying logged in

1. Unauthorized Access

  • Physical Access: Anyone with physical access to your device can gain unauthorized entry to your accounts.
  • Remote Access: Remote attackers can exploit vulnerabilities to access your logged-in sessions.

2. Malware and Keyloggers

  • Credential Capture: Malware and keyloggers can capture your login credentials, compromising your accounts.
  • Undetected Compromise: These attacks can occur without your knowledge, leading to potential data breaches.

3. Session Hijacking

  • Cookie Theft: Attackers can steal your session cookies to take control of your active session.
  • Impersonation: This allows them to impersonate you and access your accounts without needing your password.

4. Device Security

  • Stolen Device: If your device is stolen, an attacker can access all your logged-in accounts.
  • Compromised Device: A compromised device can lead to data breaches and unauthorized actions performed in your name.

5. Device Switching

  • Manual Logout: You may need to manually log out and log back in when switching devices, which can be time-consuming.
  • Workflow Disruption: This inconvenience can lead to frustration and encourage you to leave yourself logged in, increasing security risks.

The Importance of Passphrases in Digital Security

Passphrases are a critical component of digital security, offering a robust alternative to traditional passwords. Unlike passwords, which are often short and complex, passphrases are longer and easier to remember, making them an effective tool for enhancing your online security. Here’s an in-depth look at why passphrases are important and how to use them effectively:

Enhanced Security Through Length and Complexity

  • Longer Length: Passphrases are typically longer than passwords, often consisting of multiple words or a full sentence. This increased length adds significant complexity, making them harder to crack through brute-force or dictionary attacks.
  • Easier to Remember: Despite their length, passphrases are usually easier to remember because they can be based on memorable phrases or sentences. This reduces the temptation to write them down or use weak, reusable passwords.

Resistance to Common Attack Vectors

  • Brute-Force Attacks: The longer length of passphrases exponentially increases the number of possible combinations, making brute-force attacks much less effective.
  • Dictionary Attacks: Passphrases that include random words or phrases are less susceptible to dictionary attacks, where attackers use lists of common words and phrases to guess passwords.

Memorability and User Experience

  • Easy to Recall: Passphrases are designed to be memorable, often incorporating meaningful phrases or sentences that are easy to recall. This reduces the reliance on password managers or written records.
  • Improved User Experience: The ease of remembering passphrases enhances the overall user experience, making it more likely that users will adhere to strong security practices without feeling inconvenienced.

Implementation and Best Practices

  • Create Strong Passphrases: To create a strong passphrase, use a combination of random words, numbers, and special characters. Aim for a minimum length of 16 characters, and avoid using easily guessable words or patterns.
    • Example: “CorrectHorseBatteryStaple42!” combines random words with numbers and special characters, creating a strong and memorable passphrase.
  • Avoid Personal Information: Do not include personal information, such as your name, birthdate, or address, in your passphrases. Personal information can be easily guessed or obtained through social engineering tactics.
  • Use Passphrases for Critical Accounts: Apply passphrases to your most critical accounts, such as email, online banking, and social media. These accounts often contain sensitive information and should be protected with the strongest credentials possible.
  • Enable Two-Factor Authentication (2FA): Even with strong passphrases, enabling 2FA adds an extra layer of security. 2FA requires a second form of verification, such as a code sent to your phone or a biometric scan, making it harder for attackers to gain access to your accounts.

Passphrase Management

  • Use a Password Manager: While passphrases are designed to be memorable, using a password manager can help you generate, store, and manage them securely. A password manager ensures that your passphrases are encrypted and accessible only to you.
  • Regularly Update Passphrases: Periodically update your passphrases to maintain strong security hygiene. If you suspect that one of your accounts has been compromised, change your passphrase immediately to mitigate the risk of further unauthorized access.
  • Avoid Sharing Passphrases: Sharing passphrases should be avoided whenever possible. If you must share, use secure methods such as encrypted notes or password manager sharing features to ensure that your passphrases remain confidential.

Passphrases vs. Passwords

  • Complexity and Memorability: Passphrases offer a balance between complexity and memorability. While passwords can be complex, they are often short and harder to remember, leading to weak or reused credentials. Passphrases, on the other hand, are longer and easier to recall, enhancing both security and user experience.
  • Security Benefits: The increased length and complexity of passphrases make them more resistant to common attack vectors, such as brute-force and dictionary attacks. This enhanced security benefit makes passphrases a superior choice for protecting your online accounts.

Password Managers

Password managers are indispensable tools in the digital age, offering a secure and convenient way to store, manage, and autofill passwords, passphrases, and other sensitive information. With the increasing number of online accounts and the complexity of password requirements, password managers provide a solution that enhances security while reducing the hassle of remembering multiple credentials. Here’s an in-depth look at password managers.

What Are Password Managers

Password managers are applications designed to securely store and manage passwords and other sensitive data. They use encryption to protect your information, ensuring that only you can access it. With a password manager, you only need to remember one master password or passphrase to unlock your entire vault of credentials.

Why Use Password Managers

Password managers offer enhanced security by generating and storing complex, unique passwords for each account, protecting you from attacks. They provide convenience with auto-fill features, saving time and reducing errors. Centralized management makes it easy to update and organize credentials, while secure sharing ensures that sensitive information is protected even when shared. Password managers also offer peace of mind with regular updates, disaster recovery options, and additional features like secure note storage. By using a password manager, you can significantly enhance your online security and convenience. Here are some key features:

Secure Storage: Encrypts and securely stores passwords.
Auto-Fill: Automatically fills in login credentials.
Password Generation: Creates strong, random passwords.
Sync Across Devices: Keeps passwords secure and accessible anywhere.
Secure Sharing: Safely shares passwords without revealing them.
Two-Factor Authentication (2FA): Adds an extra security layer.
Secure Notes: Stores sensitive information like credit card details.
Password Health Checks: Identifies and prompts updates for weak passwords.
Browser Extensions: Provides easy access and integration with web browsers.
Offline Access: Ensures login capability without an internet connection.

Two-Factor Authenticator

Two-Factor Authentication (2FA) is a crucial security measure that enhances the protection of your online accounts by requiring two forms of identification. This additional layer of security significantly reduces the risk of unauthorized access. Here are the detailed benefits of implementing 2FA:

  • Enhanced Security: 2FA improves account security by requiring two forms of verification. Even if one factor (e.g., your password) is compromised, the account remains secure unless the second factor is also breached. For example, if a hacker obtains your password, they still need physical access to your phone or another device to complete the authentication process.

  • Protection Against Phishing: Phishing attacks are common methods used by cybercriminals to steal passwords. With 2FA, even if you enter your password on a phishing site, the attacker still needs the second factor to access your account, adding a robust layer of defense against phishing attempts.

  • Defense Against Brute-Force Attacks: Brute-force attacks involve trying multiple password combinations until the correct one is found. 2FA mitigates this risk because an attacker would need to guess both your password and the second authentication factor, making successful attacks much less likely.

  • Securing Sensitive Information: Many organizations store sensitive and proprietary information in their online accounts. By enabling 2FA, businesses can ensure that only authorized individuals have access to this critical data, reducing the risk of data breaches and unauthorized access.

  • Compliance and Regulatory Requirements: Various industries have regulatory requirements that mandate enhanced security measures. Implementing 2FA helps organizations comply with these regulations, such as those set by the National Institute of Standards and Technology (NIST), which recommends the use of multi-factor authentication.

  • User Convenience: While 2FA adds an extra step to the login process, it is generally user-friendly and quick. Many 2FA methods, such as push notifications or biometric scans, are seamless and do not significantly impact the user experience, making 2FA an attractive option for both individuals and organizations.

  • Reduced Reliance on Passwords: Passwords are often the weak link in security chains due to their susceptibility to theft, guessing, and phishing. 2FA reduces reliance on passwords alone by introducing a second factor, such as a physical token or biometric data, which is harder to replicate or steal.

  • Protection Against SIM Swapping: SIM swapping involves an attacker transferring your phone number to a new SIM card, allowing them to intercept SMS-based 2FA codes. While SMS-based 2FA is not the most secure method, using an authenticator app or physical token as the second factor can mitigate this risk.

  • Support for Multiple Devices: Many 2FA solutions support multiple devices, allowing users to receive authentication requests on various platforms, including smartphones, tablets, and computers. This ensures that users can always access their accounts securely, regardless of the device they are using.

  • Easy to Implement: Enabling 2FA is straightforward and can be done through most online services’ security settings. Users simply need to follow the prompts to set up their preferred second factor, whether it’s an authenticator app, SMS, or hardware token.

  • Cost-Effective: Implementing 2FA is often cost-effective, as many services offer it for free. The benefits of enhanced security far outweigh the minimal costs associated with setting up and maintaining 2FA.

  • Peace of Mind: Knowing that your accounts are protected by an extra layer of security provides peace of mind. Users can be confident that their personal and sensitive information is better safeguarded against cyber threats.

  • Support for Biometric Authentication: Modern 2FA solutions support biometric authentication methods, such as fingerprint scans and facial recognition. These methods are convenient and secure, as they are unique to the individual and difficult to replicate.

  • Reduced Risk of Account Takeover: By requiring a second factor, 2FA significantly reduces the risk of account takeover. Even if an attacker knows your password, they still need physical access to your device or token to gain entry, making it much harder for them to take control of your account.

  • Protection Against Man-in-the-Middle (MitM) Attacks: MitM attacks involve an attacker intercepting communication between a user and a service to steal sensitive information. 2FA helps protect against these attacks by ensuring that even if the initial password is compromised, the second factor provides an additional layer of security.

SMS and Email Alerts

While SMS-based two-factor authentication (2FA) is widely used due to its convenience, it comes with several significant drawbacks that can compromise your security:

About SMS Alerts

Susceptibility to SIM Swapping:

One of the major vulnerabilities of SMS-based 2FA is its susceptibility to SIM swapping attacks. In a SIM swap, an attacker tricks your mobile carrier into transferring your phone number to a new SIM card, allowing them to intercept your SMS messages, including 2FA codes.

 

Phishing and Social Engineering: 

SMS messages can be easily phished or spoofed, making it possible for attackers to trick you into providing your 2FA codes or other sensitive information. Social engineering tactics can also be employed to manipulate you into divulging your 2FA details.

 

Network Issues and Delays: 

Reliance on mobile network connectivity means that SMS messages can be delayed or even lost, especially in areas with poor signal strength. This can lead to failed authentication attempts and potential lockouts from your accounts.

 

Lack of End-to-End Encryption: 

Most SMS messages are not end-to-end encrypted, meaning they can be intercepted and read by unauthorized parties, including your mobile carrier and potential eavesdroppers.

 

Device Theft or Loss: If your phone is stolen or lost, an attacker can potentially gain access to your SMS messages, including 2FA codes, unless you have additional security measures in place, such as a PIN or biometric lock.

 

Carrier Vulnerabilities: 

Mobile carriers themselves can be targets of attacks, and if compromised, they can expose your SMS messages to attackers. This adds another layer of risk to relying on SMS for 2FA.

About Email Alerts

Email, on the other hand, offers several advantages over SMS for 2FA and alerts, making it a more secure and reliable option:End-to-End 

Encryption:

Many email providers offer end-to-end encryption, ensuring that your messages, including 2FA codes, are secure from eavesdropping and interception. This provides a higher level of security compared to SMS.

 

Reduced Risk of SIM Swapping:

Since email is not tied to a specific SIM card, it is not vulnerable to SIM swapping attacks. As long as you have access to your email account, you can receive 2FA codes and alerts securely.

 

Better Network Reliability:

Email is typically more reliable than SMS, as it does not depend on mobile network connectivity. You can access your email from anywhere with an internet connection, reducing the risk of missed 2FA codes or alerts.

 

Enhanced Security Measures:

Email providers often offer additional security measures, such as two-step verification, spam filters, and phishing protection, which can further secure your 2FA process.

 

Easier Recovery Options:

If you lose access to your email account, many providers offer robust recovery options, such as security questions, backup email addresses, and account recovery processes, making it easier to regain access to your 2FA codes.

 

Wider Compatibility:

Email is a universal communication method, making it widely compatible with various services and devices. This ensures that you can use email-based 2FA across all your accounts and platforms.

 

Better for Public Wifi:

When you are out in public and need to use wifi, its better to use email as you can use a VPN to secure your connection, whereas with SMS you are relying on your carrier to protect your data.
